Getting ready for Planet Comicon Part 2

so I have my dome all glue together and all the logic mounts done except for the rear PSI.  I also painted my dome panels all done in time for Planet Comicon.  Sitting at the Con table Friday I finally loaded all the logics into the dome and turned them on.  It looks great except for the PSIs.   The Front PSI works but seems pretty dim behind all the diffusers.  The rear PSI doesn't work at all.  The board is good since it works when I put it on the front chain so it must be the sketch.  Loaded the default sketch and the rear PSI works again.  Its pretty dim too behind the diffusers so I need to try adjusting the intensity setting in the sketch.
